Title: Continuous structure forming method and the resulting product
Inventor: PAYNE LEROY
IPC: B29C59/04
Filed: 1993-03-18
Abstract: A method of forming a continuous structure includes the following steps. A plurality of reactive resin forming materials are preselected. A first of the resin forming materials is applied over a major surface of a porous blanket in a first preselected pattern including a plurality of independent sections. A second of the reactive resin forming materials is applied over a major surface of the porous blanket in a second preselected pattern including a plurality of independent sections spaced from the independent sections of the first pattern. Substantially simultaneously, the reactive resin forming materials in the respective patterns are intermixed. A liquid resin mixture is formed over the porous blanket. The treated blanket is positioned in a preselected configuration while the blanket is deformable and adhesive. The blanket is set in that configuration. Also, the resulting continuous structure.

Patent CA-2096905-A1 (CA)
Inventor: KOERFER GUENTER
IPC: H01J61/72
Filed: 1993-05-25
Abstract: To increase the resistance of a tubular compact fluorescent lamp against breakage, particularly at the cross-connecting portion (4) of a U-bent discharge vessel having two leg portions (2, 3), the cross-connecting portion is shaped to have generally parabolic cross section, in which the cross-sectional area of the parabola is about the same as the cross-sectional area of the generally circular leg portions of the U-shaped discharge vessel (1). This provides for better distribution of the glass material of which the discharge tube is made, and hence greater resistance to breakage. The parabolic cross section is terminated at the inner side of the U-bend by an essentially flat, or slightly curved base surface (16), merging with rounded corners (16a) with the parabolic side surfaces. Preferably, the relationship of the radius of curvature (R p) at the apex of the parabola to the radius of curvature(R B) of the transition regions (16a) at the corners between the base (16) and the parabolic side surfaces is between about 0.7 and 1.1. The uniform distribution of wall thickness reduces manufacturing defects and breakages.

Title: Method and apparatus for ablative heat transfer
Inventor: BROWN DOUGLAS B
IPC: C10G1/10
Filed: 1991-12-02
Abstract: This invention pertains to a method and apparatus for rapid heat transfer using surface-to-surface heat transfer of a solid or semi-solid feedstock against an inner surface of a containment vessel. The vessel is torus or helically shaped so that a feedstock (and products) can be conveyed through the vessel at a velocity which sustains the feedstock against the outer periphery of the internal surface of the vessel as it transits the vessel. The reaction vessel can be used for pyrolysis of materials such as waste rubber, municipal solid waste, plastics or papers so as to recover valuable petrochemical-based liquid reaction products as well as solid reaction products. The reaction vessel may also be used for gasification and combustion reactions.

Title: Treatment of waste
Inventor: CONOCHIE DAVID STEWART
IPC: A62D101/22
Filed: 1992-12-07
Abstract: A method of destroying organic waste in a bath of molten metal and slag contained in a vessel (3) is disclosed. The method comprises injecting organic waste into the bath to form a primary reaction zone (13) in which the organic waste is thermally cracked and the products of the thermal cracking which are not absorbed into the bath are released into the space above the surface of the bath. The method further comprises injecting an oxygen-containing gas towards the surface of the bath to form a secondary reaction zone ( 17) in the space above the surface of the bath in which the oxidizable materials in the products from the primary reaction zone (13) are completely oxidized and the heat released by such oxidation is transferred to the bath. In order to facilitate efficient heat transfer from the secondary reaction zone (13) to the bath, the method further comprises injecting an inert or other suitable gas into the bath to cause molten metal and slag to be ejected upwardly from the bath into the secondary reaction zone (17).
